Delhi Police Commissioner SN Shrivastava said today that the technology has been used extensively to investigate over 750 cases related to the riots in northeast Delhi that have arrested more than 200 people.
At the annual press conference at the Delhi police headquarters, Shrivastava said 755 FIRs had been registered in connection with the riot and that his force had ensured a “free and fair” investigation.

“They are aware of the riots that resulted in 53 deaths and 581 injuries. The riots peaked on February 24-25 last year. A total of 755 FIRs have been recorded and we have advised that no one has made a complaint about it their complaint had not been recognized, “he said. He said three SITs had been set up to investigate the cases.
One of the cases was registered to expose the conspiracy behind the riot, which was being investigated by the Delhi Police Special Cell, while the remaining cases were being investigated by the northeastern district, he said.
The Delhi police chief commented on the use of technology, saying 231 defendants were arrested on the basis of CCTV footage.
“Of these, 137 were identified by FRS (Facial Recognition System) when cross-checked against criminal records, and the remaining 94 were identified by driver’s license photos,” he said.
He said the investigation team used video analytics and FRS to analyze CCTV footage to identify the accused re-deleted data from electronic devices and use geographic location to determine the presence of the suspects and drone mapping for crime scene reconstruction.
The use of DNA fingerprinting, e-Vahan database, facial recognition, fund flow analysis, and forensic teams that include physical, chemical, biological and ballistic analysis of videos and photos from open sources were also used to investigate the cases , he added.
